Can Geckos Eat Hornworms?

Yep, Geckos love munching down on hornworms as much as they love any other worm. While some geckos might be picky eaters, in general, you can get a gecko to eat a hornworm in just a few tries.

Hornworms are a rather yummy and squishy treat for leopard geckos, and they are full of nutrients and a lot of moisture, which makes them a good snack for a change of diet.

Here’s a video of a leopard gecko named Senator munching down a large blue hornworm (and looking rather smug afterward):

Now that you know that, you might have several questions about them, for example: which hornworms to feed, what size, what color, how much to feed, when to feed, and so on. So, for the rest of the article, we are going to focus on those answers.

Can Crested Geckos Eat Hornworms?

Yes, a crested gecko can also eat hornworms. They are a lovely little snack to add to their usual diets, and you can add them once or twice every month. Hornworms are low on fat and contain no chitin, so they are perfect feeders for crested geckos.

Can Hatchling Leos Eat Hornworms?

Baby geckos and adult leopard geckos are very different in what kind of nutrients they need. They need more calcium in their diet, eat more often than adult geckos, and can only digest smaller bugs, not larger ones.

If you are feeding a baby leopard gecko, make sure that you give it food three to four times a day, and for the really hungry ones, add an extra meal on top.

But while you are doing this, the worms and other food that you give to the kiddos have to be small enough to go down their throat. They need to be able to digest what you are feeding them.

For example, if you are planning to give your baby gecko hornworms, make sure to give them the tiny ones, not the big ones that are almost about to become moths in a few days.

Here’s a small feeding chart that you can follow depending on how old your gecko is

Remember, baby geckos are super hungry from the get-go, and they are greedy as hell. You will have to control what they eat because they will put anything in their mouths.

Moreover, they need to feed much more often than adults because they metabolize food much more quickly.

Therefore, don’t give them big meals. Instead, feed them smaller hornworms, but more frequently. If you give them a larger hornworm by mistake, there are two dangers.

For one, the hornworm might get caught in the hatchlings’ tongues. Secondly, even if the babe gobbles it up, she is going to be super hungry once again pretty quickly.

Make sure you don’t buy hornworms in bulk. Hornworms grow up much quicker than geckos, so you would end up with a lot of big hornworms with no gecko to feed them to.

Can You Feed Hornworm Pupae to Leos?

The Pupa stage of the hornworm occurs after its larval stage and is the last stage before it turns into a moth. At this stage, the pupae start to become harder and bigger.

As long as the pupae are still not hard enough, it might be ok to feed it to your leo. But the moment you can feel hardness setting in, please don’t feed it.

Leo’s can eat pupae that are about 2.5 inches big. Anything bigger than that might end up choking them. And feeding a pupa to a baby or juvenile leo is an absolute no-no.

If you have bought some pupae from the market, make sure to treat them gently because they damage easily (because of the hardening). Feed them to your gecko one by one. Never put two or three into its habitat at once.

Are Hornworms Beneficial for Leopard Geckos?

Hornworms are about 85% moisture, 3% calcium, and 9% protein, and the rest is fat. They are one of the few feeder insects that have a high proportion of calcium in their bodies.

So if you are feeding your pet leopard gecko a hornworm, you are basically supplementing it with calcium which it cannot produce on its own.

This is a natural way of calcium supplementation instead of gut-loading your feeder insects. Hornworms also contain a good amount of phosphorus, so these worms are perfect for preventing bone diseases in geckos.

However, these bugs are not very high in protein content, so obviously, they cannot form the bulk of the diet. They are a nice occasional treat to have once in a while.

Apart from the nutritional aspect, here are a few more things that make hornworms good for leos:

• They don’t have any chitin in them. Leos can digest these worms easily.
• Leo’s can catch them easily. They move slowly and are brightly colored.
• The smaller hornworms are quite tiny and are perfect for both hatchlings and babies.
• They don’t have a lot of fat, so they don’t cause your leo to put on extra pounds.
• They are a good source of hydration.

Why Might You Not Want To Feed Hornworms to Your Leo?

There are reasons why you should think twice about making a hornworm m a regular habit for your leopard gecko.

• The protein content is a bit of a bummer. It’s much below what your leo needs.
• Hornworms are very expensive.
• Hornworms are short-lived (or rather, they become a moth quickly, so if you don’t move quickly, you will end up with a house full of moths.
• Leos love them too much. Your Leo might start rejecting other food once it gets hooked on hornworms.
• Hornworms don’t eat anything that can add calcium to their gut. So they can’t be gut loaded.

Lastly, don’t ever feed hornworms caught in the wild because they could have bacteria and fungus growing on them.

Do Leopard Geckos Like Hornworms?

Yes, they love the taste of hornworms! As we said earlier, leos tend to get addicted to the taste of hornworms and might start refusing other types of worms and insects.

That’s why it is particularly important to only feed these to them occasionally, as a treat. If you start giving your leo a lot of hornworms, it will only spell trouble.

Hornworms are not a good enough diet for geckos to live entirely on them. So if your leo gets addicted to them, it could affect their health.

In order to maintain a healthy balance, add other worms and insects to the Leo’s diet. Here are some tasty and healthy options for your leo:

• Dubia roaches
• Cockroaches
• Beetles
• Silkworms
• Mealworms
• Grasshoppers
• Crickets
• Locusts

Geckos don’t need a lot of fat. Commercially available feeders like wax worms, super worms, and butter worms are often full of fat, so they are not the perfect diet for your leo. Adding 1-2 to their diet is fine, but it should not be a staple food.

The best policy is to mix up all of these food sources and feed them to the leo rotationally.

Feeding Hornworms to Leos: How To Do It

It’s easy for geckos to feed on hornworms. These insects are slow, and it doesn’t take a lot of effort to catch them. Hornworms are 85% water, so they digest pretty easily. They also have no chitin.

The trick to adding hornworms to a gecko’s diet is to make sure that you also supplement the diet with other nutrients missing in these bugs. Here are some strategies on how you can do that.

Gut loading

Gut loading is a regular practice used to increase the nutritional level of insects and worms to make them a balanced diet. For example, hornworms are not rich in protein, so you feed them lots of protein as a part of their meal before giving them to your gecko to eat.

This makes sure that the necessary protein reaches the gecko’s body. The easiest way to do this is to start feeding these worms protein-rich foods about half a day before you plan to use them for feeding.

Unfortunately, hornworms typically prefer sweeter food options, such as tomato leaves, nightshade vegetables, tobacco leaves, and horsenettle. Therefore it’s quite hard to feed them protein-rich diets.

In any case, high-quality hornworms bought from a reputable source should have all the right nutrients already in them. So you can ignore gut-loading these worms.

Supplementation

One thing that hornworms do have plenty of is calcium. However, the calcium present in their bodies may not be enough for the needs of your leo, especially if it is a hatchling or a juvenile.

Another problem is that these lizards need Vitamin D3 to absorb calcium from food, which is another nutrient that you have to add to their diet separately.

If your leo does not have access to UV rays, you might like to add Vitamin D3 supplements to its diet, as otherwise, it can get Vitamin D deficiency.

The Calcium to Phosphorus (Ca:P) ratio of the food that you are giving to your gecko should not go beyond 2:1 under ideal conditions. Lastly, you should supplement hornworms with multivitamins, especially for hatchlings.

Dusting

Since hornworms don’t contain a lot of vitamins, and it is difficult to gut load them, it is best to dust them with the necessary nutrients before feeding them to your leo.

All you need to do is to get hold of some multivitamin powder and roll your hornworms in it for a bit. Add them to a bag of the powder and gently shake it till they are covered with the stuff.

Wrap Up

We hope we covered everything you wanted to know about feeding hornworms to your leopard gecko. These worms are an excellent source of calcium but are not that rich in protein, so you need to supplement them in other ways.

Moreover, it is best only to feed them as an occasional snack instead of feeding them regularly to your leo. Thank you for reading!
